1. Pure 4G camera inserted into the SIM card for network
The camera itself can be inserted into a 4G SIM card, and it can be connected to the 4G network after turning on. It can be connected through the serial number or QR code of the camera. Simple operation and easy to get started. The disadvantage is that the 4G SIM card is inserted into the camera. If the camera is installed at a high place, it is not convenient to replace the 4G-SIM card in the future. You need to remove it and replace it, and then install it. Of course, there is a wired surveillance video recorder with 4G cards inside. For example, this is how the general car monitoring system is connected.
Actual application: This 4G camera is widely used. For example, this is the first choice for unmanned sales machine installation monitoring.
2. Through the 4G SIM Card connected network
This 4G Cato is usually a USB type. Of course, it is also inserted through the 5V power supply of the mobile phone. It only supports wireless online and does not support the RJ45 port to access the Internet. Therefore, cable monitoring cannot be connected to the Internet in this way.
Actual application: This is a relatively common 4G monitoring solution on the Internet. The camera is an ordinary wireless camera (usually a wireless rotation camera), randomly add one or more IoT traffic cards, insert the traffic card through a 4G card tray, wireless Internet access, and then the camera connects the 4G card wireless network.
3. Through 4G router connected
4G router is an IoT high -speed router that is completely compatible with 4G/3.5G/3G/2.5G network. The flagship configuration, VPN link, industrial protection, and wide temperature design make it easier to establish a high -speed and stable wireless transmission network. Use the public LTE network to provide users with wireless remote data transmission functions. The 4G router is different from ordinary routers, but the way they connect to the external network are different, and other functions are basically the same.
The 4G router inserts the SIM card to receive the base station signal and connects to the Internet. At present, there are many 4G routers on the market, and some can only be connected to the Internet through cables, and some can connect to the Internet through the actual needs.
Actual application: If there is no broadband in the farm, you need to monitor remote monitoring, install a 4G router, and then connect the video recorder to the 4G router for network.
